NOT invited! Leonardo DiCaprio banned Lindsay Lohan from a party at his house on March 11, after she played in a checkers tournament he hosted at Bootsy Bellows in West Hollywood.

“Lindsay wasn’t even invited, but she still showed up,” a witness tells Star. “Being a nice guy, Leo allowed her in.”

Unfortunately, the Wolf of Wall Street star learned pretty quickly that good would not come out of his decision. “She was whining about everything, like not having a place to sit or not wanting certain people near her,” the spy dishes. “If she doesn’t have all the attention, she throws tantrums.”

The insider adds that LiLo’s whining became such an annoyance, that Leo had a friend kick her out after just 15 minutes! Looks like the party scene isn’t ready to take her back just yet…
